The points given:
- (−6, −2), (0, −10), (5, 2), (−1, 10)
They form a rectangle as seen in the picture.
We can notice that this is a parallelogram, as respective lines have same difference of coordinates.
So calculating only the two of the sides will be sufficient to get its perimeter:
- a = √(-1+6)² + (10+2)² = √25+144 = √169= 13
- b = √(0+6)² + (-10+2)² = √36+64 = √100 = 10
So, the perimeter:
